[0002] The present disclosure claims priority to Chinese Patent Application No. 202411344878.7, filed September 25, 2024, the entire contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0004] Currently, different configuration tables are used for random access configuration for time division duplexing (TDD) and frequency division duplexing (FDD). For TDD, the PRACH time domain resource is determined by the index of the PRACH configuration table. Specifically, the network side indicates a PRACH configuration index value to the terminal, and the terminal looks up the PRACH configuration table according to the RACH configuration index value to obtain the relevant RACH configuration parameters, such as preamble format, subframe number, parameters for calculating radio frame, starting symbol, number of PRACH slots within a subframe, number of time-domain PRACH occasions within a PRACH slot and PRACH duration, and then the PRACH time domain resource can be determined according to the above RACH configuration parameters. The design of the above PRACH configuration table is not flexible due to the limitation of overhead, and is mainly for the typical uplink and downlink configuration of TDD, so the flexibility of determining the PRACH time domain resource based on the PRACH configuration index value indicated by the network side is poor.

It can be understood that the above function modules can be network elements in a hardware device, can be software function modules running on a dedicated hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0055] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:

[0056] I. Random access resource selection

[0057] The random access procedure can be a contention-based random access procedure or a non-contention-based random access procedure. The random access procedure can be a four-step random access procedure (also called Type-1 random access procedure) or a two-step random access procedure (also called Type-2 random access procedure).

[0058] In the contention-based four-step random access procedure, a user equipment (UE) first sends Msg1 containing a preamble to the network; after detecting the preamble, the network sends Msg2 / Random Access Response (RAR) message containing the number of the preamble detected by the network and the uplink radio resource allocated to the UE for sending Msg3; after receiving Msg2, the UE confirms that at least one of the numbers of the preambles carried in Msg2 is consistent with the number of the preamble sent by the UE, and then sends Msg3 containing contention resolution information according to the resource indicated by the RAR; after receiving Msg3, the network sends Msg4 containing contention resolution information; after receiving Msg4, the UE confirms that the contention resolution information is consistent with the contention resolution information sent by the UE in Msg3, and completes the four-step random access.

[0059] The network includes uplink grant (UL grant) information in the RAR, which is used to indicate Msg3 Physical Uplink Sharing Channel (PUSCH) scheduling information, and includes RACH preamble ID (RAPID), temporary cell radio network temporary identity (TC-RNTI), time advanced (TA), and the like. If the network does not receive Msg3 PUSCH, retransmission of the Msg3 PUSCH can be scheduled in a physical downlink control channel (PDCCH) scrambled by the TC-RNTI.

[0060] For a contention-based random access procedure, different UEs randomly select preambles for transmission, so that different UEs can select the same preamble for transmission on the same time-frequency radio resource (for example, a random access opportunity (RACH Occasion, RO) resource). This situation can be understood as a preamble collision of the UEs. In this case, different UEs can receive the same RAR, and at this time, different UEs can perform Msg3 PUSCH transmission according to the scheduling information in the RAR UL grant. The network can only decode one PUSCH transmitted by a UE on one Msg3 PUSCH scheduling resource, and the PUSCH includes contention resolution information. Therefore, the network can include the contention resolution information received in Msg3 in Msg4. If the contention resolution information in Msg4 received by the UE matches the contention resolution information sent by the UE in Msg3 PUSCH, the UE considers that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.

[0061] If the contention resolution is unsuccessful, the UE reselects a RACH transmission resource and performs PRACH transmission to perform the next random access attempt.

[0062] Two-step random access (2-step RACH) procedure is introduced in NR system. The first step is that UE sends MsgA to network side. After network side receives MsgA, it sends MsgB message to UE. If UE does not receive MsgB within a certain time, UE will add one to the counter that counts the number of times of sending MsgA and resend MsgA. If the counter that counts the number of times of sending MsgA reaches a certain threshold, UE will switch from 2-step random access procedure to 4-step random access procedure. MsgA includes MsgA preamble part and MsgA PUSCH part. The preamble part is sent on RO for 2-step RACH, and the PUSCH part is sent on MsgA PUSCH resource associated with the sending of MsgA preamble and RO. MsgA PUSCH resource is a set of PUSCH resources configured relative to each PRACH slot, including time-frequency resource and DMRS resource.

[0063] II. Selection of random access resource and mapping of SSB to RO

[0064] In NR, a cell can configure multiple FDM PRACH transmission occasions (PRACH Occasions) or PRACH occasions (ROs) in one time domain location of PRACH transmission. For simplicity of description, it is referred to as RO. At one time, the number of FDM ROs can be {1, 2, 4, 8}. At one time, there are 8 RO resources distributed in different frequencies.

[0065] Random access preamble can only be transmitted on the time domain resource (RO resource) configured by the parameter PRACHConfigurationIndex, and random access preamble can only be transmitted on the frequency domain resource configured by the parameter prach-FDM, PRACH frequency domain resource n RA ∈{0,1,...,M-1}, where M is equal to the high layer parameter prach-FDM. At the time of initial access, PRACH frequency domain resource n RA From the lowest frequency RO resource in the initial active uplink bandwidth part, it is numbered in ascending order, otherwise, PRACH frequency domain resource n RAThe ROs within an active uplink bandwidth part are numbered in ascending order, starting from the lowest frequency RO.

[0066] In NR, there is a relationship between RO and the actual transmitted synchronization signal / physical broadcast channel block (SS / PBCH block, also referred to as SSB for short). One SSB can be associated with multiple ROs, or one RO can be associated with multiple SSBs, in which case different SSBs correspond to different preamble codes. Generally, the base station can use different beams to transmit different SSBs, and the corresponding UE transmits the preamble on the RO associated with the SSB. In this way, the UE selects the RO associated with the SSB with good signal strength, or the combination of RO and preamble, according to the strength of the received downlink beam / SSB, and transmits Msg1. In this way, the network can determine the SSB selected by the UE according to the received preamble RO, or the combination of RO and preamble, and transmits Msg2 on the downlink beam corresponding to the SSB to ensure the quality of the received downlink signal.

[0067] Three, random access configuration (Random access configurations)

[0068] Currently, TDD and FDD use different configuration tables for random access configuration. Table 1 is a random access configuration table for TDD.

[0069] Table 1

[0070] It can be understood that the above table 1 only shows part of the random access configuration table for TDD.

[0071] Four, PRACH time domain resource location

[0072] The PRACH resource is periodic. In time domain, different PRACH Preamble formats have different durations. The time domain location of the PRACH resource is defined by PRACH configuration period, radio frame index, subframe / slot index, starting PRACH OFDM symbol index within a slot, and the number of time domain ROs within a slot. The candidate value of the PRACH configuration period is {10, 20, 40, 80, 160} ms. The PRACH resource is only distributed in one valid radio frame (e.g. 10 ms) within each PRACH configuration period. The valid radio frame contains one or more subframes / slots. There is only one starting PRACH Orthogonal Frequency Division Multiplexing (OFDM) symbol index within each subframe / slot. There is one or more time domain ROs within a slot. In frequency domain, different PRACH Preamble formats and subcarrier spacing jointly determine the frequency domain bandwidth occupied by the PRACH. For the long Preamble format with length 839, when the PRACH subcarrier spacing is 1.25 kHz, the frequency domain bandwidth is 1.08 MHz, which corresponds to 6 Physical Resource Blocks (PRBs) with PUSCH subcarrier spacing 15 kHz.

[0073] V. Full Duplex Mode

[0074] In 5G mobile communication system, full duplex is enhanced to adapt to diversified scenarios and service requirements. The main scenarios of 5G include Enhance Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communications (URLLC), massive Machine Type of Communication (mMTC), which require high reliability, low latency, large bandwidth, wide coverage, etc.

[0075] In NR, configuring full duplex operation can significantly improve the latency and coverage performance of Time Division Duplexing (TDD) systems.

[0076] Subbands non-overlapping Full duplex can improve transmission latency and enhance coverage.

[0077] For a downlink (DL) slot (configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated), the network configures a DL bandwidth part (BWP) for the UE, and for an uplink (UL) slot, the network configures a UL BWP for the UE. For example, slot 1 and slot 4.

[0078] Referring to FIG. 2a, for a full duplex scenario, there are the following cases:

[0079] Case 1: DL BWP is configured, such as slot 1;

[0080] Case 2: DL BWP and UL sub band are configured, such as slot 2.

[0081] Referring to FIG. 2b, for a UL slot (configured by tdd-UL-DL-ConfigurationCommon, or tdd-UL-DL-ConfigurationDedicated), there are the following cases:

[0082] Case 3: UL BWP is configured, such as slot 4;

[0083] Case 4: UL BWP and DL sub band are configured, such as slot 5.

[0084] For a seamless bidirectional forwarding detection (SBFD) operation, an SBFD sub band is composed of one resource block (RB) or one set of contiguous RBs with the same transmission direction.

[0085] A time unit (e.g., slot or symbol) in which a gNB uses an SBFD operation can be referred to as an SBFD time unit (e.g., slot or symbol).

[0086] Referring to FIG. 2c, for Rel-15, a base station and a UE can only transmit or receive at one time. For a Rel-18 gNB full duplex, a gNB can simultaneously transmit and receive, and a UE can only use a half duplex mode and can only transmit or receive at one time. For a UE full duplex, a gNB and a UE can simultaneously transmit and receive.

[0087] For UE-side full duplex, a larger guard bandwidth (GB) (larger than the GB of base station frequency division (FD)) can be needed to suppress self-interference, see FIG. 2d.

[0088] For a communication device, simultaneous UL reception and DL transmission can cause self-interference. In order to ensure the transmission of the interfered direction, the communication device needs to have self-interference cancellation capability, for example, a reserved guard band between the reception frequency band and the transmission frequency band, but this will reduce the throughput of the UE.

[0089] The resource determination method provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings and some embodiments and application scenarios thereof.

[0090] Please refer to FIG. 3, which is a flowchart of a resource determination method provided by an embodiment of the present application, which can be executed by a first device, as shown in FIG. 3, including the following steps:

[0091] Step 301, the first device receives first configuration information;

[0092] Step 302, the first device determines PRACH time domain resources according to the first configuration information;

[0093] The first configuration information includes a first RACH configuration parameter, or the first configuration information includes at least two RACH configuration index values.

[0094] The first RACH configuration parameter includes at least one of the following parameters: a radio frame parameter, a subframe parameter, a starting symbol, a PRACH duration, a PRACH preamble format, first indication information, a symbol type of RACH resources in the time domain, a first parameter, a second parameter, and a third parameter.

[0095] The radio frame parameter is used to determine the radio frame in which the PRACH opportunity is located, the subframe parameter is used to determine the subframe in which the PRACH opportunity is located, the first parameter is the number of PRACH slots in one subframe, the second parameter is the number of PRACH opportunities in one PRACH slot, the first indication information is used to indicate whether to allow or not to allow cross symbol types, and the third parameter is used to determine the position of RACH resources in the SBFD pattern.

[0096] In the embodiment, the first device can include, but is not limited to, a terminal, a Customer Premise Equipment (CPE), a Tagged device, a Reduced Capability Device (RedCap Device), and the like. The terminal can include, but is not limited to, the types of the terminal 11 listed above.

[0097] In some optional embodiments, the first device can be a full-duplex-capable device or a device supporting full-duplex transmission, and the like. For example, the full-duplex can include, but is not limited to, enhanced full-duplex or SBFD, and the like.

[0098] For example, the first device can receive the first configuration information from a second device. The second device can include, but is not limited to, a network-side device, a Reconfigurable Intelligence Surface, an Intelligent Reflection Surface, a Repeater or Relay, a Satellite, and the like. The network-side device can include, but is not limited to, the types of the network-side device 12 listed above.

[0099] In an embodiment, the first configuration information includes first RACH configuration parameters, and the second device directly configures the first device with parameters for determining PRACH time domain resources. In this way, the first device can directly determine the PRACH time domain resources based on the parameters configured by the second device. This can improve the flexibility of configuring parameters for determining PRACH time domain resources, and further improve the flexibility of determining PRACH time domain resources.

[0100] The radio frame parameter is used to determine a radio frame in which a PRACH occasion is located. For example, the radio frame parameter can include a radio frame number, or the radio frame parameter can include a first value and a second value used to calculate a radio frame number. For example, the first value can represent the x parameter shown in Table 1, and the second value can represent the y parameter shown in Table 1. Alternatively, the first value can represent a PRACH configuration period, and the second value can represent an offset value. The radio frame number is also referred to as a System Frame Number (SFN).

[0101] The subframe parameter is used to determine a subframe in which a PRACH occasion is located. For example, the subframe parameter can include at least one of a subframe number, a subframe pattern, and the like.

[0102] The meanings of the above-mentioned Starting symbol, the above-mentioned PRACH duration, the above-mentioned Preamble format, the above-mentioned Number of PRACH slots within a subframe, and the above-mentioned number of time-domain PRACH occasions within a PRACH slot can be the same as the meanings of the corresponding parameters shown in Table 1, and will not be repeated here.

[0103] Exemplarily, the symbol type of the RACH resource in the time domain can include, but is not limited to, at least one of an uplink symbol, a flexible symbol, a full-duplex symbol, and the like, and the full-duplex symbol can include at least one of a first-device-side full-duplex symbol and a second-device-side full-duplex symbol; or the symbol type of the RACH resource in the time domain can include, but is not limited to, at least one of an SBFD symbol and a non-SBFD symbol, and the SBFD symbol can include at least one of a first-device-side SBFD symbol and a second-device-side SBFD symbol.

[0104] The SBFD symbol can be understood as a symbol used for SBFD transmission, such as a flexible symbol configured with an UL subband, an UL symbol configured with an UL subband and a DL subband, and the like. The non-SBFD symbol can be understood as a symbol not used for SBFD transmission, such as a flexible symbol not configured with an UL subband, an UL symbol not configured with an UL subband, an UL symbol configured with an UL subband and not configured with a DL subband, and the like.

[0105] The embodiment can flexibly provide time-domain resources for RACH transmission by configuring the symbol type of the RACH resource in the time domain, which helps to improve the RACH capacity, reduce the collision probability, and enhance the coverage performance of the uplink signal or channel.

[0106] The first indication information is used to indicate whether to allow or not to allow cross-symbol types, wherein allowing cross-symbol types can be understood as allowing one RO to cross different symbol types, such as one RO crossing an SBFD symbol and a non-SBFD symbol; and not allowing cross-symbol types can be understood as not allowing one RO to cross different symbol types, and one RO can only include one type of symbol, such as one RO only including an SBFD symbol or only including a non-SBFD symbol.

[0107] The embodiment indicates whether the cross-symbol type is allowed or not through the first indication information, which is beneficial to further improve the time domain resource of the RACH transmission, can more flexibly provide the time domain resource of the RACH transmission, helps to improve the RACH capacity, reduces the conflict probability, and enhances the coverage performance of the uplink signal or channel.

[0108] The third parameter is used to determine the position of the RACH resource in the SBFD pattern, for example, the third parameter can include the position of the RACH resource in the SBFD pattern, or the third parameter can include the offset value of the starting position of the RACH resource relative to the starting position of the SBFD pattern, and the length of the RACH resource, etc.

[0109] The SBFD pattern is used to represent the distribution of the SBFD time domain resource, etc. For example, the second device configures time slots 1, 2, 3, 6, 7, and 8 as SBFD time slots, and time slots 0, 4, 5, and 9 as non-SBFD time slots, so the SBFD pattern is 1, 2, 3, 6, 7, and 8 time slots, and the RACH time domain resource can be a subset of the SBFD pattern, for example, the RACH resource appears in time slots 1, 2, 6, and 7.

[0110] The embodiment provides the RACH time domain resource indication more flexibly through the third parameter used to determine the position of the RACH resource in the SBFD pattern.

[0111] In the related art, the PRACH time domain resource provided by the RACH configuration table is mainly for the typical TDD uplink and downlink configuration, and does not consider the uplink subband resource available in the downlink (DL) time slot of full duplex, so that the time domain resource for sending the preamble is limited to the UL time slot and the flexible time slot. In the present embodiment, the first device can be flexibly configured with various parameters for determining the PRACH time domain resource, without being limited by the RACH configuration table, so that in the full duplex scenario, the first device can be configured to send the preamble in the UL time slot and the flexible time slot, and can also be configured to send the preamble in the UL subband of the DL time slot, which can provide more PRACH transmission opportunities, not only can improve the coverage performance of the uplink signal or channel, but also can reduce the probability of random access conflict.

[0112] It is to be noted that the first RACH configuration parameter can include part of the parameter items or all of the parameter items for determining the PRACH time domain resource. For example, in the case that the first RACH configuration parameter includes part of the parameter items for determining the PRACH time domain resource, the first device can determine the PRACH time domain resource based on the parameter items included in the first RACH configuration parameter and the remaining parameter items obtained based on other manners, wherein the remaining parameter items can be understood as the parameter items other than the parameter items included in the first RACH configuration parameter among all the parameter items required for determining the PRACH time domain resource, for example, if the first RACH configuration parameter includes five parameter items, i.e., the first indication information, the symbol type of the RACH resource in the time domain, the first parameter, the second parameter and the third parameter, the remaining parameter items can include five parameter items, i.e., the radio frame parameter, the subframe parameter, the starting symbol, the PRACH duration and the PRACH preamble format, and the remaining parameter items can be obtained based on the PRACH configuration table. It is to be noted that the first indication information and the symbol type of the RACH resource in the time domain are not provided in the RACH configuration table of the related technology.

[0113] In another embodiment, the first configuration information includes at least two RACH configuration index values, the second device can indicate the at least two RACH configuration index values to the first device, and the first device can determine the PRACH time domain resource based on the at least two RACH configuration index values, for example, based on the intersection or the union of the RACH configuration parameters corresponding to each RACH configuration index value in the at least two RACH configuration index values. For example, the RACH configuration parameters corresponding to each RACH configuration index value can be obtained based on the PRACH configuration table.

[0114] For example, the second device can provide two RACH configurations to the first device, for example, one RACH configuration compatible with the legacy device (Legacy RACH configuration) and one additional RACH configuration (additional RACH configuration), each of the RACH configurations provides one RACH configuration index value, and the first configuration information can indicate the two RACH configuration index values, and the first device can determine the PRACH time domain resource based on the two RACH configuration index values.

[0115] In the related art, the second device only supports indicating one RACH configuration index value, and the first device directly queries the PRACH configuration table based on the indicated one RACH configuration index value, obtains the corresponding RACH configuration parameter, and determines the PRACH time domain resource based on the RACH configuration parameter. However, in the present embodiment, since the second device can support indicating at least two RACH configuration index values, different RACH configuration parameters can be obtained by indicating different combinations of RACH configuration index values, thereby realizing the configuration of different PRACH time domain resources. For example, the RACH configuration parameter obtained based on the combination of RACH configuration index value 1 and RACH configuration index value 2 can be different from the RACH configuration parameter obtained based on the combination of RACH configuration index value 1 and RACH configuration index value 3. Compared with the related art, more RACH time domain resource configurations can be obtained, thereby improving the flexibility of the second device in configuring the PRACH time domain resource for the first device, and further improving the flexibility of the first device in determining the PRACH time domain resource, and improving the coverage performance of the uplink signal or channel.

[0116] Optionally, the first configuration information includes the first RACH configuration parameter and a first RACH configuration index value.

[0117] In the present embodiment, the first RACH configuration index value can include at least one RACH configuration index value.

[0118] For example, as shown in FIG. 4, the resource determination method provided by the present embodiment includes the following steps: step a1, the second device sends the first RACH configuration parameter and the first RACH configuration index value to the first device; and step a2, the first device determines the PRACH time domain resource according to the first RACH configuration parameter and the first RACH configuration index value.

[0119] Exemplarily, in a case that the second device configures the first device with the first RACH configuration parameter and the first RACH configuration index value simultaneously, if the first RACH configuration parameter includes all parameter items for determining the PRACH time domain resource, the PRACH time domain resource can be determined based on the first RACH configuration parameter only, without using the parameter corresponding to the first RACH configuration index value; if the first RACH configuration parameter includes only part of the parameter items for determining the PRACH time domain resource, the first device can determine the PRACH time domain resource based on the parameter items included in the first RACH configuration parameter and the remaining parameter items obtained based on the first RACH configuration index value, wherein the remaining parameter items can be understood as the parameter items other than the parameter items included in the first RACH configuration parameter in all parameter items required for determining the PRACH time domain resource; or, in a case that the second device configures the first device with the first RACH configuration parameter and the first RACH configuration index value simultaneously, the PRACH time domain resource can be determined based on the first RACH configuration parameter and the RACH configuration parameter corresponding to the first RACH configuration index value together, for example, for the same parameter items in the first RACH configuration parameter and the RACH configuration parameter corresponding to the first RACH configuration index value, the union or intersection of the values of the two can be taken to determine the PRACH time domain resource.

[0120] The second device can configure the first device with the first RACH configuration parameter and the first RACH configuration index value in the embodiment, so that the first device can determine the PRACH time domain resource based on the first RACH configuration parameter and the first RACH configuration index value, which is beneficial to further improve the flexibility of PRACH time domain resource configuration and save resource overhead.

[0121] Optionally, the first device determines the PRACH time domain resource according to the first configuration information, including:

[0122] The first device determines the PRACH time domain resource according to the first RACH configuration parameter and the second RACH configuration parameter.

[0123] The second RACH configuration parameter is a RACH configuration parameter determined according to the first RACH configuration index value.

[0124] In the embodiment, the second RACH configuration parameter can be obtained by querying the PRACH configuration table according to the first RACH configuration index value. For example, when the first RACH configuration index value includes at least two RACH configuration index values, the RACH configuration parameter corresponding to each RACH configuration index value can be obtained by querying the PRACH configuration table respectively, and the second RACH configuration parameter can be determined based on the RACH configuration parameter corresponding to each RACH configuration index value, for example, the union or intersection of the same parameter items in the RACH configuration parameters corresponding to all RACH configuration index values is taken as the value of the corresponding parameter item in the second RACH configuration parameter; or, when the first RACH configuration index value includes at least two RACH configuration index values, one RACH configuration index value can be selected from the at least two RACH configuration index values based on a protocol predefined rule or a rule indicated by the second device, and the RACH configuration parameter corresponding to the selected RACH configuration index value is taken as the second RACH configuration parameter.

[0125] In the embodiment, the first device determines the PRACH time domain resource according to the first RACH configuration parameter and the second RACH configuration parameter, which is beneficial to further improve the flexibility of determining the PRACH time domain resource.

[0126] Optionally, the first device determines the PRACH time domain resource according to the first RACH configuration parameter and the second RACH configuration parameter, including:

[0127] The first device determines the PRACH time domain resource according to the first RACH configuration parameter and the third RACH configuration parameter.

[0128] The third RACH configuration parameter is a parameter in the second RACH configuration parameter, and the parameter item in the third RACH configuration parameter is different from the parameter item in the first RACH configuration parameter.

[0129] For example, if the first RACH configuration parameter includes the first indication information, the symbol type of the RACH resource in the time domain, the first parameter, the second parameter and the third parameter, the third RACH configuration parameter can include the radio frame parameter, the subframe parameter, the starting symbol, the PRACH duration and the PRACH preamble format.

[0130] In the embodiment, for the same parameter item in the first RACH configuration parameter and the second RACH configuration parameter, the first device preferentially uses the parameter in the first RACH configuration parameter, and for the parameter item not included in the first RACH configuration parameter, the parameter in the second RACH configuration parameter is used, so that the determined PRACH time domain resource is more matched with the actual application scenario requirement while ensuring that the PRACH time domain resource can be determined.

[0131] Optionally, the first device determines the PRACH time domain resource according to the first RACH configuration parameter and the second RACH configuration parameter, comprising:

[0132] The first device determines the PRACH time domain resource according to the fourth RACH configuration parameter.

[0133] The fourth parameter of the fourth RACH configuration parameter is the intersection or union of the fourth parameter of the first RACH configuration parameter and the fourth parameter of the second RACH configuration parameter.

[0134] The fourth parameter is the same parameter item in the first RACH configuration parameter and the second RACH configuration parameter.

[0135] In the embodiment, for the same parameter item (the fourth parameter) in the first RACH configuration parameter and the second RACH configuration parameter, the intersection or union of the parameter in the first RACH configuration parameter and the parameter in the second RACH configuration parameter is used, for example, if the first RACH configuration parameter includes the subframe number and the second RACH configuration parameter includes the subframe number, the intersection or union of the subframe number of the first RACH configuration parameter and the subframe number of the second RACH configuration parameter is used.

[0136] It can be understood that, for the parameter item not included in the first RACH configuration parameter and included in the second RACH configuration parameter, the parameter in the second RACH configuration parameter is used for the parameter in the fourth RACH configuration parameter except the above-mentioned fourth parameter, for example, if the first RACH configuration parameter does not include the PRACH duration and the second RACH configuration parameter includes the PRACH duration, the PRACH duration of the second RACH configuration parameter is used; for the parameter item not included in the second RACH configuration parameter and included in the first RACH configuration parameter, the parameter in the first RACH configuration parameter is used, for example, if the first RACH configuration parameter includes the first indication information and the second RACH configuration parameter does not include the first indication information, the first indication information of the first RACH configuration parameter is used.

[0137] In the embodiment, for the same parameter item (the fourth parameter) in the first RACH configuration parameter and the second RACH configuration parameter, the intersection or the union of the parameter in the first RACH configuration parameter and the parameter in the second RACH configuration parameter is used to determine the PRACH time domain resource, which is beneficial to further improve the flexibility of determining the PRACH time domain resource.

[0138] Optionally, the first configuration information includes at least two RACH configuration index values, and the first device determines the PRACH time domain resource according to the first configuration information, including:

[0139] The first device determines the RACH configuration parameter according to each RACH configuration index value in the at least two RACH configuration index values respectively, to obtain at least two RACH configuration parameters;

[0140] The first device determines the PRACH time domain resource according to the fifth RACH configuration parameter;

[0141] The fifth parameter of the fifth RACH configuration parameter is the intersection or the union of the fifth parameter of the at least two RACH configuration parameters, and the sixth parameter of the fifth RACH configuration parameter is the sixth parameter in one RACH configuration parameter of the at least two RACH configuration parameters.

[0142] The fifth parameter is a protocol predefined parameter item or a second device indicated parameter item, and the sixth parameter is a parameter item in the at least two RACH configuration parameters except the fifth parameter.

[0143] In the embodiment, for the fifth parameter of the fifth RACH configuration parameter, the intersection or the union of the fifth parameter of the at least two RACH configuration parameters is used; for the parameter (the sixth parameter) in the fifth RACH configuration parameter except the fifth parameter, the sixth parameter in one RACH configuration parameter of the at least two RACH configuration parameters can be used, for example, the sixth parameter in any one RACH configuration parameter of the at least two RACH configuration parameters can be used, or the sixth parameter in one RACH configuration parameter selected from the at least two RACH configuration parameters according to a protocol predefined rule or a second device indicated rule can be used.

[0144] In the embodiment, for the protocol predefined or second device indicated parameter item, the intersection or the union of the parameter in the at least two RACH configuration parameters is used, and for the parameter item except the protocol predefined or second device indicated parameter item, the parameter in one RACH configuration parameter of the at least two RACH configuration parameters is used, which is beneficial to further improve the flexibility of determining the PRACH time domain resource.

[0145] Optionally, the first device determines PRACH time domain resource according to the first configuration information, including:

[0146] In a case where the first condition is met, the first device determines the PRACH time domain resource according to the first configuration information;

[0147] The first condition includes at least one of the following:

[0148] The PRACH preamble format is a specific preamble format;

[0149] The symbol type of the PRACH resource in the time domain is a specific symbol type.

[0150] In the embodiment, the specific preamble format can be predefined by a protocol or indicated by the second device. For example, the specific preamble format can be a long preamble format, such as at least one of preamble format 0, preamble format 1, preamble format 2, and preamble format 3. The specific symbol type can also be predefined by a protocol or indicated by the second device. For example, the specific symbol type can be an SBFD symbol.

[0151] For example, in a case where the first condition is not met, the first device can determine the PRACH time domain resource based on a related technology manner, such as determining the PRACH time domain resource based on a RACH configuration index value indicated by the second device.

[0152] In the embodiment, in a case where the first condition is met, the first device determines the PRACH time domain resource according to the first configuration information, which is beneficial to determining the corresponding PRACH time domain resource according to the symbol type or the preamble format, thereby improving the coverage performance of the uplink signal or channel.

[0153] Optionally, the radio frame parameter includes at least one of the following: a first value for calculating a radio frame number, and a second value for calculating a radio frame number.

[0154] For example, the first value can represent the x parameter shown in Table 1, and the second value can represent the y parameter shown in Table 1; or the first value can represent a PRACH configuration period, and the second value can represent an offset value.

[0155] For example, the radio frame number can be calculated based on the following formula: n SFN mod x = y, wherein x represents the first value, y represents the second value, n SFN represents the radio frame number, also known as the system frame number, and mod represents the modulus symbol.

[0156] Exemplarily, the second device can configure at least one of the first value and the second value to replace the corresponding parameter of the PRACH configuration table, so as to improve the flexibility of the PRACH configuration, facilitate better matching of the time domain configuration of the SBFD, and thus facilitate increasing the capacity of the PRACH and improving the coverage performance of the uplink signal or channel and reducing the collision probability.

[0157] Exemplarily, for the (x, y) parameter pair, the second device can configure at least one of the following (x, y) parameter pairs or (x, y) parameter pair sets:

[0158] (16, 1); (8, 1); (4, 1); (2, 1); (1, 0); (2, 0); (4, 0); (16, 0); (8, 2); {(16, 1), (16, 2)}; {(8, 1), (8, 2)};...; {(8, 1), (8, 2), (8, 3), (8, 4)}.

[0159] In some optional embodiments, the second device can indicate which (x, y) parameter pair is used by using a bitmap, for example, as shown in Table 3, the second device indicates two (x, y) parameter pairs (8, 1) and (8, 2).

[0160] Table 3

[0161] In another optional embodiment, the second device can indicate the (x, y) parameter pair by using an index value. For example, as shown in Table 4, the second device configures four (x, y) parameter pairs, and can use 2 bits to indicate which one of the four (x, y) parameter pairs.

[0162] Table 4

[0163] Optionally, the subframe parameter includes at least one of the following: a subframe number, a subframe number pattern.

[0164] In an embodiment, the subframe parameter can include a subframe number, for example, 0, 1 and 4, that is, there is an RO in the subframe whose subframe number is 0, 1 and 4. This embodiment directly configures the subframe number, which facilitates the first device to quickly determine the subframe number of the subframe in which the RO exists.

[0165] In another embodiment, the subframe parameter can include a subframe number pattern, wherein the subframe number pattern can reflect the arrangement position of the subframe in which the RO exists. For example, in the case of a subframe number pattern of 00010, it indicates that the fourth subframe of a half frame exists RO; in the case of a subframe number pattern of 01100, it indicates that the second and third subframes of a half frame exist RO. By configuring the subframe number pattern, the subframe number pattern can be repeatedly used in multiple time units (e.g., half frames or radio frames, etc.), which is beneficial to save the subframe configuration overhead.

[0166] In some optional embodiments, the second device can configure the above-mentioned subframe parameter to replace the corresponding parameter (e.g., subframe number) of the PRACH configuration table, which can improve the flexibility of PRACH configuration, better match the configuration of SBFD, and thus increase the capacity and coverage of PRACH and reduce the collision probability.

[0167] In some optional embodiments, in the case where the second device configures the first device with a first RACH configuration index value, the second device can configure the above-mentioned subframe parameter to indicate a subframe number different from the subframe number corresponding to the first RACH configuration index value. For example, for the TDD RACH configuration table of FR1, when the network configures a RACH configuration index value of 17, it indicates that the subframes with subframe numbers of 4 and 9 exist RO, and then the network side device can configure the subframes with at least one of the subframe numbers of 0, 1, 2, 3, 5, 6, 7, and 8 to exist RO, which is beneficial to improve the flexibility of subframe number configuration and increase the capacity and coverage of PRACH.

[0168] In some optional embodiments, the second device can configure at least one subframe parameter or a set of subframe parameters, and can indicate which subframe parameter or set of subframe parameters to use through a bitmap or an index value. The indication method of the bitmap or the index value can refer to the related description of the foregoing embodiments, which will not be repeated here.

[0169] Optionally, the subframe parameter is a subframe parameter of a first time unit, and a subframe parameter of a second time unit is determined according to the subframe parameter of the first time unit.

[0170] In some optional embodiments, the first time unit and the second time unit are both time units in which a PRACH opportunity exists, and the time unit includes a radio frame or a half frame of a radio frame.

[0171] Exemplarily, the first time unit can be a specific half frame of a radio frame, for example, a front half frame or a rear half frame; or the first time unit can be a specific radio frame in a system frame, for example, a first radio frame in which a PRACH opportunity exists. The second time unit can be a time unit different from the first time unit, for example, the first time unit is a front half frame of a radio frame, and the second time unit can be a rear half frame of the radio frame.

[0172] In some optional embodiments, the second time unit can be predefined by a protocol or can be indicated by the second device.

[0173] The subframe parameter of the second time unit is determined according to the subframe parameter of the first time unit, for example, if the subframe parameter of the first time unit only includes a subframe number, a subframe number pattern can be determined based on the subframe number of the first time unit, and then a subframe number in which an RO exists in the second time unit can be determined based on the subframe number pattern; if the subframe parameter of the first time unit includes a subframe number pattern, a subframe number in which an RO exists in the second time unit can be directly determined according to the subframe number pattern.

[0174] The embodiments are described below in conjunction with examples:

[0175] The second device can only configure subframe numbers in which ROs exist in a front half frame of a radio frame, and apply a pattern of the subframe numbers of the front half frame to a rear half frame of the radio frame, for example, the second device indicates that subframes with subframe numbers 0, 1, 2 and 3 have ROs, and the configuration is 1111, and then subframes with subframe numbers 5, 6, 7 and 8 also have ROs, as shown in Table 5, where a TDD pattern is taken as an example of a 30 kHz subcarrier.

[0176] Table 5

[0177] The embodiments can determine the subframe parameter of the second time unit through the configured subframe parameter of the first time unit, can guarantee the flexibility of the subframe parameter configuration, and can save the overhead of the subframe parameter configuration.

[0178] Optionally, in a case where the first device receives the second indication information, the subframe parameter of the second time unit is determined according to the subframe parameter of the first time unit.

[0179] The second indication information is used to indicate a repeated subframe number pattern.

[0180] In the embodiment, when the second device indicates the repetition of the subframe number pattern, the first device determines the subframe parameter of the second time unit based on the subframe parameter of the first time unit. For example, 1 bit can be used to indicate whether the subframe number pattern is repeated, where 0 indicates repetition and 1 indicates no repetition, or 1 indicates repetition and 0 indicates no repetition.

[0181] It should be noted that the second indication information and the subframe parameter can be sent to the first device by the same signaling, or the second indication information and the subframe parameter can be sent to the first device by different signaling respectively.

[0182] Optionally, the subframe parameter comprises a subframe number pattern, the subframe number pattern being a subframe number pattern of a time unit, and a subframe number pattern of a third time unit being the subframe number pattern.

[0183] The third time unit comprises at least one time unit in a time unit in which the PRACH opportunity is located, and the time unit comprises a radio frame or a half frame of a radio frame.

[0184] In the embodiment, the third time unit can be predefined by a protocol, for example, the third time unit can be predefined by the protocol as the first half frame of a radio frame, or the third time unit can be predefined by the protocol as the second half frame of a radio frame, or the third time unit can be predefined by the protocol as comprising the first half frame and the second half frame of a radio frame, so that the first half frame and the second half frame both apply the subframe number pattern; or indicated by the second device, for example, the second device can indicate that the third time unit is the first half frame of a radio frame, or the second device can indicate that the third time unit is the second half frame of a radio frame, or the second device can indicate that the third time unit can comprise the first half frame and the second half frame of a radio frame, so that the first half frame and the second half frame both apply the subframe number pattern. For example, the second device can use 1 bit to indicate whether the subframe number pattern is applied to the first half frame or the second half frame, where 0 indicates the first half frame and 1 indicates the second half frame, or 1 indicates the first half frame and 0 indicates the second half frame.

[0185] For example, the second device indicates that the subframe number pattern is 0001, and the half frame indication bit is 1, where 0 is the first half frame and 1 is the second half frame, so that the subframe with the subframe number 8 exists RO, as shown in Table 6.

[0186] Table 6

[0187] In the embodiment, by configuring the subframe number pattern in a time unit, the subframe number in which the RO exists in the at least one time unit can be determined based on the subframe number pattern, so that the flexibility of the subframe parameter configuration can be ensured while the overhead of the subframe parameter configuration is saved.

[0188] Optionally, the symbol type comprises at least one of:

[0189] a first device-side SBFD symbol;

[0190] a second device-side SBFD symbol;

[0191] a non-SBFD symbol.

[0192] The first device-side SBFD symbol can be understood as a symbol configured for SBFD operation of the first device. The second device-side SBFD symbol can be understood as a symbol configured for SBFD operation of the second device.

[0193] The non-SBFD symbol can be understood as a symbol not configured for SBFD operation. For example, the non-SBFD symbol can comprise at least one of a symbol for uplink transmission only, a symbol for downlink transmission only, a flexible symbol, etc.

[0194] Optionally, the third parameter comprises a position of the RACH resource in a SBFD pattern;

[0195] or,

[0196] the third parameter comprises at least one of a first offset value, a length of the RACH resource or a number of fourth time units;

[0197] wherein the first offset value is an offset value of a starting position of the RACH resource relative to a starting position of the SBFD pattern, and the fourth time unit comprises a PRACH subframe, a PRACH slot, a PRACH symbol or a PRACH occasion.

[0198] In an embodiment, the second device can directly configure the position of the RACH resource in the SBFD pattern, for example, can indicate by bitmap which time domain resources (e.g. subframes, slots or symbols) can be used for RO starting from the starting position (e.g. subframes, slots or symbols) of the SBFD symbol pattern, which facilitates the first device to quickly determine the RACH resource.

[0199] In another embodiment, the second device can indicate an offset value, a resource length or a number of resources, etc. for the first device to determine the position of the RACH resource in the SBFD pattern, which is advantageous for saving resource overhead.

[0200] The first offset value is an offset value of a starting position of the RACH resource relative to a starting position of the SBFD pattern, for example, an offset value of a starting symbol of the RACH resource relative to a starting symbol of the SBFD pattern, or an offset value of a starting subframe of the RACH resource relative to a starting subframe of the SBFD pattern, or an offset value of a slot symbol of the RACH resource relative to a starting slot of the SBFD pattern, and the like.

[0201] In some optional embodiments, the first offset value can also be an offset value of a starting position of the RACH resource relative to a predefined or configured reference point, for example, the reference point can be the start of a starting symbol of a radio frame.

[0202] For example, in a case where the third parameter includes the first offset value and the length of the RACH resource, the starting position of the RACH resource can be determined based on the first offset value, and then the position of the RACH resource can be obtained according to the starting position of the RACH resource and the length of the RACH resource; in a case where the third parameter includes the first offset value and the number of fourth time units, the starting position of the RACH resource can be determined based on the first offset value, and then the position of the RACH resource can be obtained according to the starting position of the RACH resource and the number of fourth time units.

[0203] It can be understood that, in a case where the third parameter only includes the first offset value, the length of the RACH resource or the number of fourth time units can be predefined by a protocol or determined based on other manners; similarly, in a case where the third parameter only includes the length of the RACH resource or the number of fourth time units, the first offset value can be predefined by a protocol or determined based on other manners, which is not limited in the embodiment.

[0204] For the starting symbol, for example, the second device can configure the starting symbol to replace the corresponding parameter of the PRACH configuration table, so as to improve the flexibility of the PRACH configuration, facilitate better matching of the SBFD configuration, and then facilitate increasing the capacity and coverage of the PRACH and reducing the collision probability.

[0205] For example, the second device can configure at least one starting symbol as follows: 0, 2, 5, 6, 7, 8, 9. It can be understood that the starting symbol of the embodiment is not limited to the above values.

[0206] In some optional embodiments, the second device can indicate which starting symbol is used through a bitmap or an index value, and the indication manner of the bitmap or the index value can refer to the related description of the foregoing embodiments, which is not described herein.

[0207] For the first parameter, i.e., the number of PRACH slots in a subframe, the second device can configure the first parameter to replace the corresponding parameter in the PRACH configuration table, so as to improve the flexibility of the PRACH configuration, facilitate better matching of the SBFD configuration, and thus facilitate increase of the capacity and coverage of the PRACH and reduction of the collision probability.

[0208] For example, the second device can configure at least one first parameter as follows: 1, 2. It can be understood that the first parameter in the embodiment is not limited to the above values.

[0209] In some optional embodiments, the second device can indicate which first parameter, i.e., the number of PRACH slots in a subframe, is used by means of a bitmap or an index value. The indication manner of the bitmap or the index value can be referred to the related description in the foregoing embodiments, and will not be described here.

[0210] For the second parameter, i.e., the number of PRACH opportunities in a PRACH slot, the second device can configure the second parameter to replace the corresponding parameter in the PRACH configuration table, so as to improve the flexibility of the PRACH configuration, facilitate better matching of the SBFD configuration, and thus facilitate increase of the capacity and coverage of the PRACH and reduction of the collision probability.

[0211] For example, the second device can configure at least one second parameter as follows: 1, 2, 3, 6, 7. It can be understood that the second parameter in the embodiment is not limited to the above values.

[0212] In some optional embodiments, the second device can indicate which second parameter, i.e., the number of PRACH opportunities in a PRACH slot, is used by means of a bitmap or an index value. The indication manner of the bitmap or the index value can be referred to the related description in the foregoing embodiments, and will not be described here.

[0213] For the PRACH duration, the second device can configure the PRACH duration to replace the corresponding parameter in the PRACH configuration table, so as to improve the flexibility of the PRACH configuration, facilitate better matching of the SBFD configuration, and thus facilitate increase of the capacity and coverage of the PRACH and reduction of the collision probability.

[0214] For example, the second device can configure at least one PRACH duration as follows: 0, 2, 4, 6, 12. It can be understood that the PRACH duration in the embodiment is not limited to the above values.

[0215] In some optional embodiments, the second device can indicate which PRACH duration is used by a bitmap or an index value, and the indication manner of the bitmap or the index value can refer to the related description of the foregoing embodiments, which will not be repeated here.

[0216] Optionally, the first configuration information comprises the first RACH configuration parameter, and the first device receives the first configuration information, comprising:

[0217] The first device receives at least one first configuration information;

[0218] The first device determines the PRACH time domain resource according to the first configuration information, comprising:

[0219] The first device receives third indication information, and the third indication information is used to indicate the first configuration information in the at least one first configuration information;

[0220] The first device determines the PRACH time domain resource according to the first configuration information indicated by the third indication information.

[0221] In the embodiment, the second device can pre-configure at least one first configuration information for the first device, and then can indicate which first configuration information is used by the first device to determine the PRACH time domain resource. For example, the first device can be indicated to use which first configuration information to determine the PRACH time domain resource by a bitmap or an index value. In this way, the flexibility of the parameter configuration used to determine the PRACH time domain resource can be ensured, and the configuration overhead can be saved.

[0222] Optionally, the first device determines the PRACH time domain resource according to the first configuration information, comprising:

[0223] The first device determines the PRACH time domain resource according to each configuration information in the at least two configuration information respectively, and obtains at least two PRACH time domain resources, wherein the at least two configuration information comprises at least two first configuration information, or the at least two configuration information comprises at least one first configuration information and at least one second configuration information, and the second configuration information comprises one RACH configuration index value;

[0224] In a case where there is resource overlap between the first PRACH time domain resource and the second PRACH time domain resource, the target PRACH time domain resource is valid, where the target PRACH time domain resource is one of the first PRACH time domain resource and the second PRACH time domain resource, and the first PRACH time domain resource and the second PRACH time domain resource are any two of the at least two PRACH time domain resources.

[0225] In this embodiment, the determination of the PRACH time domain resource based on the first configuration information can refer to the related description of the foregoing embodiments, which will not be described here. The PRACH time domain resource is determined based on the second configuration information, for example, a RACH configuration index value based on the second configuration information is used to query a PRACH configuration table to obtain corresponding RACH configuration parameters, and the PRACH time domain resource is determined based on the RACH configuration parameters.

[0226] The first PRACH time domain resource and the second PRACH time domain resource can be any two of the at least two PRACH time domain resources. The resource overlap can include partial resource overlap or complete resource overlap.

[0227] The target PRACH time domain resource can be any one of the first PRACH time domain resource and the second PRACH time domain resource, or the target PRACH time domain resource can be predefined by a protocol or indicated by the second device. For example, in a case where there is resource overlap between the PRACH time domain resource determined based on the first configuration information and the PRACH time domain resource determined based on the second configuration information, the PRACH time domain resource determined based on the first configuration information can be predefined by the protocol to be valid.

[0228] Exemplarily, for a UE supporting an SBFD capability, when receiving network-configured RACH configuration 1 and RACH configuration 2, if the RO configured by RACH configuration 1 and the RO configured by RACH configuration 2 overlap, for example, partially overlap or completely overlap in the time-frequency domain, the UE determines which RO of the RACH configuration is valid according to a rule predefined by the protocol or configured by the network. For example, if the RO of RACH configuration 1 is valid, the RO of RACH configuration 2 overlapping the RO of RACH configuration 1 is invalid, and the UE will not initiate random access using RACH configuration 2; if the RO of RACH configuration 2 is valid, the RO of RACH configuration 1 overlapping the RO of RACH configuration 2 is invalid, and the UE will not initiate random access using the RO resource of RACH configuration 1.

[0229] Exemplarily, in a case that there is a third PRACH time domain resource in addition to the at least two PRACH time domain resources, the third PRACH time domain resource can be considered valid, where the third PRACH time domain resource does not overlap with all PRACH time domain resources except the third PRACH time domain resource in the at least two PRACH time domain resources.

[0230] Optionally, the first PRACH time domain resource is determined according to a rule predefined by a protocol or a rule configured by the second device.

[0231] For example, a PRACH time domain resource corresponding to specific configuration information can be predefined by a protocol to be valid, for example, it can be agreed by a protocol that a PRACH time domain resource corresponding to first configuration information is valid; or which configuration information corresponds to a valid PRACH time domain resource is indicated by the second device.
